The Revenge affair. An eye for an eye. Adult “tit for tat.” These are affairs done in retaliation for a partner’s affair or due to mistreatment by the marital partner. In many cases, a Betrayed Spouse has an affair to “even the score” — and may make sure that their Wayward Spouse knows they did it.
But it’s a dangerous, immature and self-defeating response to being cheated on, which can backfire in many ways.
These actions almost always lead to separation and divorce.
